A couple of interesting articles on hydrogen. Firstly even the Guardian is not sure how ‘Green’ hydrogen is:
‘Tunisia is one of the driest countries in Africa, and has just suffered three years of drought. Yet the EU sees the country as key to producing “green hydrogen” for export to Europe. The trouble is, this fuel is obtained by splitting water into oxygen and hydrogen with electricity generated by renewable sources. Tunisia has lots of sun but precious little fresh water.’
‘Producing green hydrogen in Europe is not impossible. But it is expensive compared with fossil fuels, with even wind-based generation needing larger subsidies. Without big government support packages, it remains an open question whether European consumers would be prepared to foot the very significant price rises needed to go green in this way.’
One again the solution is government (consumer) subsidies.
The next one via the Engineer is looking at the requirements to convert Europe to hydrogen:
‘According to the report, 25 projects at a scale of 3GW electrolyser and 400KTPA need to be operating commercially by 2030 to meet the EU’s target. The report found that the timeline required to deliver these projects is likely to be a minimum of eight years and timelines beyond 10 years are probable.’
To achieve that would need 25 Hinkley Point C size nuclear power plants or around 225GW of wind turbines (assuming a 33% load factor).
Realistic?
